This invention relates toimprovements in shores, and particularly tothat kind of shore which is used for supporting forms for concretefloors and the like.

The principal object of the present invention is to provide a simple andinexpensive construction whereby the range of adjustability of anadjustable shore may be considerably increased.

A further object of the invention is to provide a shore having a frameadjustable on a support with a. head bearing member which may be readilyand quicky removed from the frame and another of a different lengthquick- 1y substituted therefor without the use of special tools.

To these and other ends, the invention consists in the construction andarrangement of parts that will appear from the following descriptionwhen read in conjunction with the accompanying drawings, the novelfeatures being pointed out in the claims following the specification.

In the drawings:

Figure 1 is a front elevation of an adjust able shore showing one way ofcarrying out the invention applied thereto;

Figure 2 is a transverse section taken substantially on line '22 ofFigure 1, and look- Figure 3 is a fragmentary side elevation of partsshown in Figure 2;

Figure 4; is a perspective view of one of the brackets for retaining thehead bearing memher on the frame;

' Figure 5 is a perspective View of a supporting member for the headbearing member;

Figure 6 is a section on line 66 of Figure 1, and 7 Figures 7 and 8 areperspective views of a slightly modified form of bracket.

Referring s ecifically to the drawings in which like re erence numeralsrefer to the same part in all the figures, 1 is the base or support ofan adjustable shore of well known type and construction. This postcomprises a tubular upright member having a spreader 2 at its upper endwhich is slidably engaged by the side members 3 of a frame. The spreader2 has outwardly extending lugs being in the direction of the arrow atsaid line;

tween whichsthe sidemembers 3 are guided in their vertical orlongitudinal movements.

'The side members 3 have clamping members fl mounted on their lowerenolswhich extend inwardly and are pivoted together insuch a manner'as toclamp the post 1 between them to support the frame thereon. Theconstruction is such that when the side members are raised relatively tothe post, the clampingv members are disengaged therefrom, permittmg theframe to be moved longitudinally relative to the post, but when the sidememing bracket 5 showninperspective in Fig- 1 ure 5. This supportingmember or bracket 5 may be formed of sheet material, andcomprises ahorizontal supporting wall 6'substantially square or rectangular inform, and on opposite sides has downwardly projectmg flanges 7. Theseflanges 7 maybe provided with openings 8' whereby the support is securedin the frame by means of bolts, although it might be secured in theframe by any other suitable means." The opposite front and rear edges ofthe supporting member are provided with upwardly projecting flanges'9adapted to engage thesides-of ahead bearing member'lO resting with itslower'end on the support 5 and serve to retain the head member betweenthe side members '3 of the frame. j Y r I The side members 3 extendabove the support 5 and at their upper ends each is provided with abracket'generally referred to by the numeral 12. Since these bracketsare similar in construction, except for being right and left, adescription of one will suflice. Each of said brackets comprises anouter wall member 13 and an-inner wall-member 14 integral therewith butspaced therefrom to form a channel between them. These inner and outerwalls engageopposite sides of the top of the side members 3 to whichthey'are. secured by any suitablemeans, as .bybolts member which liesbetween the inner and outer walls of the bracket, and the member.

or lug 16 projects forwardly and outwardly over the front wall of theside member. By this construction, the bracket is readily and :quicklypositioned on: the side member of the frame.

- The bottom of the head member is seated on thesupportfi between thesidemembers and the flanges 9 on the support, which fixes it againstmovement in all directions horizon'tally. The member 10 extends upwardlyfrom this support between the side members 30f the frame andverticallyabove said side .members, and atits top has secured theretoahead 20ofany usual or well known vconstruction. The rear wall ofthe headsupporting member engages the inwardly 'pro- ,jecting flanges 15 of'thebrackets 12, as shown in Figure-2', which retain it from rearward.movement from the frame. Secured to the front wall ofthe' head .memberat-a point oppositethe flanges 15 by means of a bolt or ..otherwise isatie member 21 in the form of a strap preferably .formed'of sheetmaterial,

. andwhich projects laterallyover the front .wallsof the -side members3, asat 22. :Each

of the projections'122is provided with an opening through which thecorresponding projection orlug16'on the-associated bracket -14 isadapted to project.

, Suitable means are providedfor securing .the tie member to-the bracket12 to prevent forward movement thereof and the head bearing member 10engaged thereby and to which itis secured. In the embodiment illustratedherein, said means comprises wedgeshaped members23 adapted. to beinserted in openings provided therefor in the projections '16 and. toengage the front wall of the tie .member21and secure it and the headmember in the frame. Vertical openings are .shownin the projections .16..However, they may extend ina horizontal direction or additional.h'orizontalopenings may be provided sothatFthe wedges may be insertedin a horizontal direction. In thisposition, they may be "readily removedor replaced when the :s'horehead andforms supported thereon arepositioned as near as possible to the top of the frame. 7 p

1 From the preceding, it will be understood that the extension orheadsupporting mem ber '10i1can'rea'dily be demounted' from the frame "by.removing the wedges 23 from the projections 16. The head supportingmember with the tie bar 21 can then be inclined forwardly from theflanges 15 and removed from the frame 3 and support 6. By this means, anew extension head member of the side members and to which the tiemember :21 may be secured. By providing'extension head members ofdifferent lengths, it is possible to secure shores of a widerange ofheights or provided with different types of heads, all using the postand frame of standard adjustable shore.

. In order to prevent loss of the wedges 23 and to have them convenientforuse when mounting a new extension member on the frame, they may besecured to-the ends of suitable flexible members,.such as the chains 24,the other ends of whichuare secured to rings 'or hooks 25 convenientlyprovided therefor on the outer walls of the brackets 14.

To secure the extension member against lateral movement or vibration'inthe shore frame, bearing members may be provided therefor.

In the present embodiment such bearing membersare shown i'n'the formiofangle irons 26. The angle irons 26 are secured -to the members-3 of theframeand project inwardly between said members and the extension member10. It will thus be seen that these angle irons'prevent movement of theex tension, member in'one direction and the.

base of the head bearing-member and the side 7 members of theframe. Thiscould-be done by cutting the flanges 7 andbending portions in oppositedirections to provide both upwardly and downwardly projecting flanges.-1

. In Figures 7 and 8 slightly modified forms of brackets 12 areillustrated. These are similar, except that like the brackets 12 theyare right and left,fand only one will be described in detail. Thebrackets 12? are preferably constructedof sheet material and'eachcomprises an outer wall 30 and an inner wall 31 spaced therefrom butconnected therewith by means of a spacing wall 32. By this con-'struction, the walls 30=and 31 are connected with opposite sides'ofth'ewall 32 and ar ranged substantially at right angles thereto. Theinnerand top wall-sare extended forwardly to provide a projection or lug33 having a top wall 3% in the planeof the top wall 32 and forming anextension thereof adjacent its inner side, and a side wall 35 in theplane of the side wall 31 and connected with the top wall 34. The wall34 is provided with a slot or opening 36 and the wall 35 with aslot oropening 37. t its rear end, the inner wall 31 is provided with a flange38 arranged substantially at right angles thereto.

The brackets 12 are adapted to be arranged at the tops of the sidemembers 3 of the frame in a manner similar to the brackets 12. The topwall 32' engages the top of the side member which is arranged betweenthe inner and outer walls 30 and 31. The flange 38 engages the rear wallof the head bearing member.

When the head bearing member 10 is arranged in the frame between theside members, the member 22 carried thereby engages the lugs 33 whichpass through the openings therein, and to which it may be secured by thewedges 23 inserted in the openings 36, as will i be understood byreference to Figure l of the drawings. If desired, the wedges may beconnected by flexible chains 24: with the bracket, the outer wall ofwhich may be provided with a ring or eyelet 39 in which the chain may besecured.

In case it is desirable to use a very short shore in which the head, onwhich the forms are supported, is very near the top of the frame, or inwhich a T-head is mounted directly on the top of the frame, the wedgesmay be arranged in the horizontal openings 37 of the lug 33. In thisarrangement, neither the head nor the forms supported thereon interferewith the removal or replacement of the wedges.
